Looks like a game similar to Hell Let Loose but has similarities to Squad.
You play as the British instead of the US.

Players will be given the option to fight with the British Airborne Division, British XXX Corps or several branches of the German Army, such as the Wehrmacht or the Waffen SS. It’s a rare opportunity to experience the intense battlefield that was the Battle of Arnhem, which stretched across farms, woods, villages and city areas. Each area is being accurately recreated from archival references that range from street level to aerial images. Whether you’re jumping out of a plane, resupplying friendlies or operating a tank you will find multiple reasons to drop back into the battlefield in this grand scaled representation of a WW2 setting never explored in a large multiplayer environment.
Here’s a thing about mod teams who become developers: they know better than anyone how to support fan-made content. When veterans of the beloved Battlefield 2 mod Project Reality made their standalone shooter, Squad, they also gave their community an SDK powered by Unreal Engine 4.
Two years on, thanks to those tools, Squad has birthed another studio and another standalone shooter: Periscope Games and their WWII combat simulation, Post Scriptum.
